a) It is given that $36\mathrm{\%}$ of the Americans believe in ghost and $37\mathrm{\%}$ believe in astrology among 1,249 Americans.

The assumption for inference of independent samples:

The response variable should be categorical data.

The random samples should be collected independently.

The sample sizes should be large. That is, in each group the number of success points and the number of failure points should be at least 10.

Here the both proportions are calculated from same samples. That is, the both responses are dependent to each other.

Therefore, it is not possible to use independent sample test.

b) For doing the inference of independent samples, there should be two different groups in which the proportion should be known. In other words, it can be said that in each sample it should be known that how many people support astrology and how many people didnt

We have studied 2 different test statistics, z, and X2. Explain the similarities in;

1. How each test statistic is calculated

2. How each test statistic is used to determine if the sample statistic provides enough evidence against the null hypothesis to reject it.

*i saw another answer on here but it didn't go in depth so im still confused

An educational psychologist wishes to know the mean number of words a third grader can read per minute. She wants to make an estimate at the $99\%$ level of confidence. For a sample of $1869$ third graders, the mean words per minute read was $25.3$. Assume a population standard deviation of $5.3$. Construct the confidence interval for the mean number of words a third grader can read per minute. Round your answers to one decimal place.
